GARING FOR WASHING-MACHINES.

Application led March 2G, 1917.

To all whom t may concern Be it known that I, WILLIAM JAcKsoNScsoonovnn, a citizen of the United States, and a resident of Belvidere,in the county of Boone and State of Illinois, have invented certain newand useful Improvements in Gearing for lVashing-lvlachines, of which thefollowing is a full, clear, and exact specification.

My invention is concerned with gearing for washing machines, and isdesigned to produce a gearing of the class described that shall besuitable primarily for hand-operated lever washing-machines of thevacuum or pounder type, in which the operating mechanism extends upwardthrough the bottomv of the tub.

It is concerned more especially with a gearing of the class described inwhich the {1y-wheel rotates in a horizontal plane, and

also with a novel form of mechanism for rotating the spider carrying thecups on the non-rotating shaft that reciprocates up and down through thebottom of the tub.

To illustrate my invention, I have annexed hereto foursheets ofdrawings, lin which the same reference characters are used to designateidentical parts in all the figures. of which,-`

I yhave shown my invention as applied to e5 the ordinary tub 10 havingthe four :legs 11,

the bottom 12, and the lid 1'3 which is hinged Specification of LettersPatent.

on the top of the tub in any suitable man ner so that it can be liftedto remove the contents or observe the operation of the ma.- chine. rIogain additional space for the gearing, I preferably employ the cap 14ecovering an aperture l5 in the lid located centrally of the tub.

Pivoted in a fulcrumed bracket 16 suitably secured on the side of thetub is the operating l1and-lever l?, which may be of any desiredconstruction, and which may be provided with the stirrup 18 at its lowerend, so that foot-power can also be applied. Pivotally connected nearthelower end of the hand lever 17 is the pitman I9, the other end of whichis pivoted on the eccentric bearing pin 20 mounted in the bevelgearwheel 21 mounted to rotate on the horizontal stub shaft 22 pinned inthe bearing bracket 23, `which in turn is secured, as by the set screw9.4, on the upper end of the verticalV bearing shaft 25, Ythe lower endof which is seated in and supported by the bearing Q6 formed in 'themain horizontal portion 27 of a bearing bracket which is secured on thetwo cross pieces 98 which are secured to and connect the lower portionsof the legs l1. T he last-mentioned bearing bracket has the pair ofhorizontal portions 29, each of which has the short upright. portions 30having the shape of an angle iron, and running into the inclinedportions 3l having the same cross section, which inclined portions inturn run into theelon'f` gated vertical portions 3;?, which in turn arepreferably connected atV their upper ends by the horizontal plate 33which rests against the under side'of the bottom of the tub and isconveniently secured thereto by the nut Sil screwed on the threaded`lower end of the vertical bearing-sleeve 35, which is mounted in thecenter of the bottom of the tub, it having the horizontal flange 36resting on said bottom, as clearly seen in Fig. l. To steady` themovement of the gearing and avoid the possibility` of its stopping ondead centers, I journal onv the upright bearing? shaft ,25, between thevbracket 9.51 and the bearing 2G, the hub of a heavy fiy-wheelll, whichhas the bevel pinion-38 secured there on meshing with thebevelgear-wheel 21, so that as the handle 17 is swung back and forth slowly.,the fiy-wheelgi will be rotated at a comparatively high speed. y

Mounted to reciprocate in the vertical bearing-sleeve tmisfthe .verticalshaft 3l), y

which has the spider 40 secured on its upper end by the mechanism whichwill be hereinafter described. Secured on the lower end of this shaft 39is a guide plate having the collar 41 at its back, which is pinned tothe lower end of the rod 39, the guide plate proper 42 having a pair ofparallel, horizontal flanges between which reciprocates the elongatedsliding block 43 pinned on the Vadjacent end of the shaft 20, which isfree to turn in its bearing in the bevel gear-wheel 21. By theconnections thus described, it will be obvious that the shaft 39 will bereciprocated each time the handle 17 is reciprocated, and it willfurther be observed that the guide plate 42 is in turn guided in itsvertical movement byY its contact with the vertical portions 32 ofthemain bearing bracket located beneath the tub.

The vspider 40 has the central hub 44 and the downwardly and outwardlyextended arms 45, which have the plurality, preferably three, of cups 46secured on the ends thereof to engage the clothes being washed in theVcustomary manner. The spider is free to rotate on the upper end of theshaft, which isprovided with the annular groove 47, into which is swungthe latchpiece 48,

best seen in Fig. 10, which is pivoted at 49 and can swing'back andforth in the horizontal recess 50 formed in the hub 44 to accommodateit. A latch 51 is pivoted to the hub at 52 and swings down over thelatch 48 and holds the same in its operative position. With theconstruction just described, it will be obvious that the spider 40 isfree to rotate on the upper end of the shaft 39, but that it can bereadily removed, when desired, by raising the lid, raising the latch 51,and finally swinging out the latch 48. By this simple connection, I caneasily remove the spider and the cups 46, as is desirable in putting ina fresh lot of clothes or in wringing out those that have'been alreadywashed.

Togive the spider 40, 'and consequently the cups 46, slight angularmovement about the shaft 39 at each reciprocation so that the cups willstrike the clothes in a new place each time, VI employ the follow ingmechanism-z Secured near the upper end of fthe shaft i 39, as best seenin Fig. 5, by the set-screw 53,is the collar 54, in which is mountedeccentrically the rod 55, the upper end of which is circular and uisfree to rotate in the circular aperture in the collar 54 through whichit passes. y A flanged collar 56 'secured onthe upper end of the rodlrests o n the collar 54, and nivoted loosely on lthe upper end ofIthis-collr-ar `-,56, as bythe pin 5.7is a dog 58, the 'shape of whichis best seen in Y, the overweighted nose of which tends to engagethelteeth '59 formed on theunder side ofthe hub 44, preferably by beingstamped into periphery of theA circularV plate 60 secured on the underside of the hub. The' portion of the rod 55 below the collar 54 issquare in cross section, and cooperates with a snugly fitting squaredaperture 6l formed at one side in the top of the sleeve 35. This sleeve35 carries the rib 62 extending along one side thereof, and the aperture6l is located in the rib 62. The squared aperture 61 leads into allarger cir-V cular aperture 63 extending the vlength of the rib 62 toaccommodate the twisted portion of the rod 55, which is twisted so as tocausey it to be given a slight rotation as it rises and falls throughthesquared aperture 61 during lthe reciprocation of the rod 39. Thisrotation causes the dog 58 to swing over a sufficient number of ratchetteeth 59V out its purposes, it will be understood that i it is capableof modifications, and that I do not desire to be limited in theinterpretation of the following claims eXcept as may be necessitated bythe state of the prior art.
